To all wiwme't may concern:

Be it known that we, JAMES B. Rene SNYDER and HENRY G. Scrrwnnnrnn,citizens of the United States, residing at Philadelphia, in the State ofPennsylvania, have in vented new and useful Improvements inPrinting-Presses, of which thefollowing is a specification.

This invention relates to printing'presses, particularly to rotaryprinting presses, and has for itsobject to provide a simple, compactmachine in which the form cylinder, impression cylinder and take-offcylinder are arranged inlparallel at the top of the frame, their axeslying in a common horizontal. plane. Above the impression and take-offcylinders and normally overlying the same is a feed table upon which thesheets tobe printed are placed and automatically fed to the impressioncylinder, said table being hinged to the front of the machine at the topthereof in such position that it may be swung upwardly and away from theaforesaid cylinders to expose them to view and provide easy accessthereto. [it

the rear of the machine the inking mechanism is carried in a swingingframe hinged to the main frame on a vertical axis whereby said frame andinking mechanism may he swung to one side entirely free of the formcylinder giving ready access thereto. lhe feed table and inkingmechanism hinged to the machine frame in the manner forth may be quicklyand easily swung away therefrom to completely expose the several workingcylinders and enable the operator to quickly change the form on the formcylinder or the cylinder itself, renew the blots-- keton the impressioncylinder, and do other thing necessary thereto, or to the off cylinder.In the drawings, Figure 1 is a perspective view of the complete pressready for printing. Fig. 2 is a similar view with the feed table andinking mechanism swung open to expose the form, impression and takeoffcylinders.

lln the drawings, 10 and 11 are two up right frame plates on oppositesides of the machine that are connected together by suitable cross-barsand braces which whole form the main frame of the printing press. At thetop of the main frame near the rear thereof is iournaled a form cylinderin Letters Patent.

front of which is an impression cylinder 13 while in front of theimpression cylinder is a take-ed cylinder '14, the latter cylinder, asis common in printing presses, being made of a plurality of spacedrings'mounted on ashaft, each of said rings forming a complete circle,or a portion of a circle, as circumstances demand. These three cylindersare arranged in parallel relation with their axes lying in a commonhorizontal plane, as shown, near the top of the main frame, whereby thetops of the cylinders project above the frame as clearly shown in Fig.2, that easy access may be had thereto.

At the rear of the machine is arranged a swinging frame 15 hinged on avertical stem 16 to the side plate 10, said swinging frame carrying theentire inking mechanism 17 of the printing press. The swinging frame 15when closed against the machineframe of the printing press as in Fig. 1carries the inking mechanism into operative relation with theform-cylinder 12, and when swung outwardly into the position shown in Fi2, or farther if desired the form cylinder is fully exposed and anoperator may without trouble change the form upon the cylinder to suitthe demand of his work, or remove the cylinder and insert a new one inits place with no inconvenience. The rolls of the inking mechanism whenthe swinging frame open, are also in a convenient position to beremoved, cleaned and changed as When the swinging frame is in closedposition, as in Fig, 1, it is held firmly in place by means of alatch orother fastc' ing 18 thatengages with a socket in the side frame 11,

Pivoted in bearings 19 on the front of the side plates 10, 11, near thetop thereof, is a feed table 20 that overlies and normally obstructsaccess to the impression roll 13 and take up roll 14, said table havingdepend ing legs 21 affixed to a horizontal shaft 22 that turns in thebearings 19 when the table swung upwardly to expose the impression takeoff cylinders as in Fig. 2. The i d table may be raised directly by handor in the manner shown in the drawings, wherein a toothed segment 23 isutilized to the outer end of the shaft 22, the teeth on said segmentbeing engaged by a worm 24 mounted. in hearings on the main frame androtated by a handle 25, By these means the feed table may be raised orlowered with very little labor.

-A printing press constructed as described is simple, compact and veryaccessible, no trouble being experienced in changing printing forms, theblanket on the impression roller, and doing any repairs that may berequired to the several cylinders. The inking rolls are also fullyexposed and in convenient position to be removed for cleaning andrenewal. But a few moments are required to open up the press as in Fig.2, or returning the swinging frame 15 and the feed table 20 to-operative positions, a few turns of the crank 25 raising or loweringthe feed table 20 and a slight turn of the latch 18 engages ordisengages the swinging frame which may then be opened or closed.

What is claimed is,

1. A printing press embodying a main frame, a form cylinder, animpression cylinder, and a take-off cylinder arranged in parallel,journaled in top of the main frame and extending. above the same, theaxes of said cylinders lying in a common horizontal plane, ahorizontally swinging frame hinged to the rear of the main frame, aninking mechanism carried thereby, said swinging frame movable on itsaxis toward the form cylinder to bring the inking mechanism intooperative relation therewith and away from said cvlinder to expose thesame and permit easy access thereto, and a vertically swinging feedtable hinged to the front of the main frame'and extending over theimpression and take-off cylinders adapted to be turned upward from saidcylinders to permit access thereto.

2. A printing press embodying a main frame, a form cylinder, animpression cylinder, and a take-off cylinder arranged in parallel,journaled in the top of the main frame and extending above the same, theaxes of said cylinders lying in a common horizontal plane, ahorizontally swinging frame hinged to the rear of the main frame, aninking mechanism carried thereby, said swinging frame movable on itsaxis toward the form cylinder to bring the inking mechanism intooperative relation therewith and away from said cylinder to expose thesame and permit easy access thereto, a vertically swinging feed tablehinged to the front of the main frame and extending over the impressionand take-off cylinders adapted to be turned upward from said cylindersto permit access thereto, and meanseompriiiing a worm, and a toothedsegment fixed to the feed table for raising and lowering the same.

structing access to said cylinders on their upper side and movabletoward and from the said cylinders and take-off, and means forpositively moving said table into a substantially vertical position togive access to said cylinders.

In testimony whereof we have hereunto set our hands in presence of twosubscribing witnesses.
